ran STATES JOHN MCCALLUM, OF BIRKENHEAD, ENGLAND.
INTERNAL-COMBUSTION ENGINE.
Application filed November 3, 1923. Serial N0. 672,500.
To all whom it may concern:
Be it known that I, JOHN MCCALLUM, a subject of the King of Great Britain and Northern Ireland, and residing at Birkenhead, Cheshire, England, have invented a certain new and useful Improvement in Internal-Combustion Engines, of which the following is a specification.
This invention relates to internal comhustion engines of the two-stroke Diesel type including a pair or pairs of coaxial cylinders separated by a diaphragm or diaphragms and each fitted with a piston, the piston or pistons nearer the crank-shaft be- 1 ing connected directly to a crosshead which in turn is connected to asingle crank, and the piston or pistons remote from the crank-shaft being connected to said crosshead by links or rods disposed externally of the cylinders so that thefiring stroke of one cylinder of the pair or of each air coincides with the compression stroke 0 the other cylinder of the pair or each pair.
The invention is characterized by the feature that the cylinders of the pair or of each pair are separated by. a single diaphragm constituted by a double combustion head which takes the form of a Waterjacketed casting and is fitted with Diesel fuel valves for both cylinders.
An upright two-stroke Diesel type engine embodying the invention is illustrated in the accompanying drawings in which Figs. 1 and 2 are sections at right angles to one another.
The engine shown comprises two coaxial cylinders 1, 2 which single diaphragm 3 and within each of Wl'llCh reci rocates a piston 4, 5 the lower piston 5-be1ng connected directly to a crossare separated by a head 6 which in turn is connected by a connecting rod 7 to a single crank (not shown), the upper piston 4 being connected to the crosshead 6 by rods 8 disposed externally of the cylinders 1, 2.
It will be seen that the firing stroke of one cylinder will coincide with the compression stroke of the other cylinder, and that the advantages of a double acting engine are obtained without the use of packing glands.
The single diaphragm 3, which is an independent part, and which separates the cylinders is constituted by a double combustion head which takes the form of a waterjacketed casting and is fitted with Diesel fuel valves 9 for both cylinders.
What I claim is In an internal combustion engine of the Diesel two-stroke type, in combination with coaxial cylinders, adouble combustion head which iscontiguous to both cylinders and separates the same, said head being a single hollow part formed separate from and thus independent of said cylinders, said head he 65 ing a hollow, water-jacketed casting, Diesel fuel valves for both cylinders fitted to said head, pistons working in said cylinders, a
cross-head to which one of said pistons is directly connected, and two connecting rods, outside of said cylinders, and through which the other of said pistons is connected to said cross-head.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
JOHN MGCALLUM.
